Application ined March 2e, 1919. serial No. 285,149.

To all-whom t may concer/n:

Be it known that I, WILLIAM H. SREN- SEN, a citizen of Denmark, residing at ,Aber- Crombie, in the county o f Richland and State of North Dakota, have invented certain new' and useful Improvements in Can- Closures, of which the following is a speciiication.

lThis invention relates to improvements in milk can closures and its prime object is to provide a closure that will provide ventilation for the contents of the canvand at the same time prevent the contents of the can from spilling should the can be p'artially tipped, completely overturned, or

` jostled while being transported over rough roads or the like. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described,

pointed out in the appended claims andillustrated in the accompanying drawings which form a part of this speci cation and in which* n Figure 1 is a-fragmentary sectional view of a milk can and of my improved closure applied thereto. l

Fig. 2 is a View of Fig. 1 with the device turned one-quarter way around. i

Fig. 3 is a plan view of the device, partly in section.

Fig. 4 is an enlarged fragmentary view of the closure.

Like reference characters denote corre-v sponding parts throughout the several views.

The reference numeral 1 denotes a milk can having the neck 2 formed with the annular grooved portion 3 and with the terminal flange 4. Adapted for releasable close fitting engagement with the neck 2 is my closure comprising the annular member 5 formed with the flange 6 -adapted to rest upon the neck ange 4, said member 5 be- Ving formed also with the oppositely disposed perforations 7 which in the operative position of the closure are disposed in alinement with the neck groove 3. member 5 'is the cap 8 formed with a central perforation 9 and with the Ventilating perforations 10, the stem 11 of a handle 12 eX- tending through the said central perforation 9 and being provided with the-disk washers 13, 14 arranged upon opposite sides of said cap. A hollow spool 15 formed with a ange 16 is secured thereby to the said cap 8, the perforations 9,

vtion of the spool 15 to Secured to the l 10 of said cap falling inside said spool.-l The barrel portion of the spool is formed with the oppositely disposed elongated slots 17 through which the. arms 18 extend that carry the dogs 19 whichV extend through the perforations 7 in the members 5 disposed in the groove 3, said dogs being of substantially smaller' diameter than' the per-A forations 7 to permit a certain lateral movement therein as the dogs are retracted. The inner or adjacent ends of the arms 18 are secured to a disk 20, provided with return spring 20x11 secured to the spool, made fast to one end of the stem 11, said arms being secured to said disk at points diametrically opposite each other. By turning the handle 12, then, from the position shown in full lines in Fig. 3 to the position shown in dotted lines the arms 18 are retracted to withdraw the dogs 19 from the groove 3 to free the annular member 5 from theneck 2. Stops 21 formed upon the cap 8 limit the turning movement of the handle l2.

' A splash shield 22 connects the barrel porthe annular member 5 below the arms 18 and to the inner surface of the lower end of the spool 15 a bellshaped member 23, formed with a central perforation 24, is secured by screws 25 which screws also secure the arms 26 to said spool, said arms extending beneath the lower end of the spool and uniting in an annular seat 27 for the ball 28 which is connected by the stem 29 to the weight 30, the upper end of said stem, which extends entirely through the ball, being 31, one face of which is in sliding engagement with the member 23, said valve being formed with a perforation 32 adapted, when the valve is stationary, to aline with the perforation 24 but when the can is tipped, overturned, or jostled the ball 28 will oscillate in its seat and so rock the velve 31 causing its apertured portion 32 to move out of alinement with the apertured portion 24 of the member 23. The valve 31 is formed with the Ventilating perforations 33 through which air may pass into the body of the can 1 when the valve 31 is stationary, the air coming through the alined perforations 32, 24 and through the perforations 10.

What is claimed is 1. In combination with a cap having a grooved neck, a closure comprising an annular member adapt'ed for insertion in said and normally are releasably secured to the sliding valve neck, said member being formed with per` forations adapted to register with the groove in said neck in the operative position of said annular member, a ca secured to said annular member, arotary handle carried by said cap, a slotted spool carried by said cap, a disk, a stem rigidly connecting said disk and handle, retractile arms connected to said disk and` extending through the slots in said spool, dogs carried by said arms and disposed in the perforated portions of said annular member and normally -in the grooved portion of said neck, and a splash shield carried by vsaid spool.

2.l In combination with a cam having a rooved neck, a closure comprising an annuar member adapted for insertion in said neck, said member being formed with perforations adapted to aline with the groove in said neck in the operative position of said annular member, a perforated cap secured to said annular member, a rotary handle secured to said leap, a stem extending from said handle into said cap, a disk made fast to one end of said stem, a slotted spool car ried by'said cap, oppositely disposed arms secured to said disk and extending through the slots in said spool, dogs carried by said arms and disposed in the perforations in said annular member for releasable insertion in the roove in said neck, and a splash shield v,carried by said spool.

3; In a can closure, a perforated cap releasably secured to the neck of the can, a

spool depending from said cap, a bellshaped perforated membe'r secured to one end of said spool, and a sliding ravity valve for said bell-shaped member Wiereby air circulation through said bellshaped member and cap is regulated in a predetermined manner.

In testimony that I claim the foregoing as my own I have hereto affixed my signature 1n the presence of two subscribing Witnesses.
